T all whom it may concern.-

Be it known that I, JOHN V. RICE, Jr., a citizen of the United States of America, and a resident of Bordentown, county of Burlington, State of New Jersey, have invented certain new and useful Improvements in Vaporizers for Gas-Engines, of which the ollowi ng is a specification.

This invention has reference to certain improvements in vaporizing apparatus for use in conjunction with gas or gasolene engines; the object ofA the invention being primarily to furnish avalve that is operated automatically.

of my improved vaporizer for gas engines,

certain parts being shown in elevation. Fig. 2 is a side elevation of a-part of the same,

, particularly the vaporizing chamber.

f or vaporizing chamber 2.

Like numerals of reference designate corresponding parts throughout the dierent gures of the drawing.

1 designates the exhaust-valve lever of a gas-engine, whichlever is ulcrumed at 15 and has its end in contact with the end of the stem 16 ofthe exhaust valve. Said lever has therefore a vibratory movement during the operation of the engine. It is only partially shown in the drawing, and the exhaust valve is not fully illustrated, it being only necessary for my resent purpose to indicate these features in t e most general way.

14 denotes an air-heating drum such as is commonly utilized with a gas'engine to heatv -air before it. is introduced into theengine. It may be of any desired construction.

A, pipe 12v leads therefrom to the gas-generating In this'pipe is an automatic suction valve 11 having a valve chamber 10; and pipe 12 also has a right# angled branch pipe furnished with a valve 13 through which cold air may enter pipe 12. This valve 15S-may have leverage devices, as 17, for o erating it if desired. Thus it will be seen tliat while heated air comes from the lheater 14, cold air is supplied through valve 13, and the air thus furnished is delivered into the chamber 2 through the valve 11.

A gasolene tank 7 is suitably supported at some convenient place and has an outlet pipe 6. From the vaporizing chamber 2 a valveprovided pipe 18 having a hand valve 19 leads to the inlet valve or' the cylinder of the gas engine and" conveys gas-thereto, or such ex losive mixture as may result 'from the union of the air and the vaporized oil in the chamber 2.

I will now explain how the gasolene is automatically fed from the pipe 6 into the chamber 2, and will accordingly describe in detail my improved` valve situated at this point;

Screwed centrall into the head 3 of the chamber 2 is a T-s aped elbow or pipe, one horizontal arm 5 of which is coupled to the outlet pipe 6, while the vertical part 4 of the 'lf-shaped elbow receives the gland 26 which is screwed thereinto as shown. The gland 26 ,is bored from end to end and contains the endwise movable rod 22. Within the elbow and below the gland 26 is a chamber 80 into which the oil is delivered from the pipe 6, and the connection 5. That part of the aforesaid elbow casting which is screwed into the head 3 and is consequently directly below chamber 30 is perforated with a coneshaped passage, within which is the coneshaped section 21 of a depending rod 20, the upper end of which is connected by screwing or otherwise (or made integral therewith) to the lower end of the rod 22. This conical rodhas a vertical movement inthe conical opening in the casting and consequently o crates as a valve tocontrol the outlet of t e oil from chamber 30. vWhen the valve is open the oil will pass through it fand drop into the vaporizing chamber 2. Loosely surrounding the upper end of rod 22 is a flanged sleeve 23, and around this sleeve, between the ilange thereof-and the top of the gland 26, is a spring 24. Pivoted to the upper end of rod 22 at its fulcrum is a rightangled bell-crank lever 25, the vertical arm of which is in a position to be struck at each vibration of lever 1 by a rejection 27 on said lever, and the horizonta Iarm of which projects above a vertical sto which limits the downward movement of t e right-angled lever 25, said-stop being adjustable to re ul'ate the extent of movement of lever 25, an consisting of a stationary verticalstandard 8 on IOO the chamber 2, the upper end thereof being screw-threaded and carryingvan adjustable nut 9.

The operation of thevoil-feeding valve 21 will be readily understood from the forego ing description of the arrangement of the parts of my invention. `At each movement of the engine lever 1 the lever 25 will be struck by the projection 27 and this will result in the lever 25 being thrown out from under the piece 27 in consequence of the other arm of lever 25 striking against the adjustable nut'Q.; and the time when such lever 25 isthus thrown out is determined by the position of the nut 9 upon the rod 8; and it willbe observed that from this movement it further results that the valve 21 will be opened more orless so as to allow oil to drop from chamber "30 into the vaporizing chamber 2. The valve 11 opens automatically by suction caused by the enginel piston, and thus the requisite amount of air is introduced into the chamber 2. By adjustingethe nut 9 the distance that the lever 25 moves at each stroke of the lever 1 may be controlled. The spring 24 closes valve 21 after each opening thereof.

Having thus described my inventionA what I claim as new and desire to secure by LettersPatent, isz- 1. In combination with 'an engine, a vapori Zing chamber having an air-inlet valve, an oil supply, a feed valve for introducing the oil into the vaporizing chamber, an angular lever connected to saidvalve and actuated by the engine, and an adjusting device for determining the throw of said angular lever, the sanjie being in the path of one of the arms of the lever, vsubstantially as described.

2. The combination with the valve-operating lever of a gas-engine, ofa vaporizing chamber, an. oil supply, an air-inlet valve on` the vaporlzing chamber, and an oil-inlet valve having a spring-provided valve rod, and an angular lever attached to the oil-inlet valve and vibrated by the contact with one of its arms of the aforesaid engine lever dur'- ing the movements of the latter.

3. The combination of the valve-operating lever of a gas-engine, of a vaporizing chamber having an air-inlet valve, an oil supply tank, a conical feed valve for introducing oil into -thevvaporizing chamber, a right-angled lever pivoted to the stem of said valve and actuated by the vibrations of the aforesaid engine lever, and an adjusting nut in the path of the right-angled lever whereby the extent of throw of said lever may be predetermined, substantially as described.
